Storage battery comprising negative plates of a wedge shaped configuration

An improved silver-zinc battery particularly suited for use in an environment where battery operation is subjected to multiple charge/discharge cycling over extended periods is described. The battery seperator system, containing a highly absorbent material continguous with the surfaces of the plates and multiple semi-permeable membranes interposed between the plates, is also characterized

Dewpoint temperature inversions analyzed

Dewpoint temperature inversion, with regard to other simultaneous meteorological conditions, was examined to establish the influence of meteorological variables on the variation of dewpoint temperature with height. This report covers instrumentation and available data, all the climatological features of dewpoint inversions, and specific special cases

Low-momentum interactions in three- and four-nucleon scattering

Low momentum two-nucleon interactions obtained with the renormalization group method and the similarity renormalization group method are used to study the cutoff dependence of low energy 3N and 4N scattering observables. The residual cutoff dependence arises from omitted short-ranged 3N (and higher) forces that are induced by the renormalization group transformations, and may help to estimate the sensitivity of various 3N and 4N scattering observables to short-ranged many-body forces.Comment: 5 pages, 8 figures, to be published in Phys.

Long-term dynamics of soil solution in Bavarian forests: Is there a recovering from acidification?

Acid deposition has damaged soils in Central Europe and has been a major source of disturbance for forest ecosystems in the last century. Although acid deposition decreased continuously since the 1990s, it is not clear how fast the damaged soils will recover. We have analysed time series of up to 20 years of precipitation, throughfall and soil solution of the top- and subsoil from 15 Level II forest monitoring sites in Bavaria (Germany). These sites represent a broad range of tree species and soil conditions. As indicators of soil acidification, we calculated the Bc/Al ratio (the ratio of the nutrient cations K, Mg and Ca to Al) and the alkalinity. Additionally, we analysed the trends in Al and SO4 concentrations. To evaluate the temporal dynamics, we extracted the trend of the time series using the model-free method Empirical Mode Decomposition. Our first results suggest that recovery from acidification, i.e. decrease of Al and increase of Bc/Al and alkalinity, is neither uniform nor continuous. We attribute the distinct responses to differences in soil properties among the studied sites

Release of Hemoglobin and Potassium from Human Red Blood Cells Treated with Triton X-100 Under the Critical Micellar Concentration

The action of detergents is thought to be connected primarily with micelle formation. However, detergent monomers can also effect biological systems. It was found in this study that human red blood cells can be disintegrated with Triton X-100 non-ionic detergent at a concentration of 0.007 %, lower than the critical micellar concentration (CMC). The time dependent release of hemoglobin and potassium was detected at 37°C and both were sigmoid in character. Although potassium was released faster than hemoglobin, a cooperative relationship between potassium and hemoglobin within the intact red blood cell is suggested by this observation
